I have a small pea sized bump around my anus that burns and itches after a bowel movement, I'm not sure if it's a hemrrhoid but I would like to know.

Go get checked. It sounds like a hemorrhoid, but no one can tell you what it is without taking a look at it. Don't be embarrassed, just go get checked and put your mind at ease.
External Hemorrhoids. Possibly. External hemorrhoids are usually seen around the anus and are painful. Have it checked by your physician to be certain.
